I am currently running El Capitan I did have to run internet restore 3 or 4 times before it would reboot normally also rebooted in Verbose mode , then I was able to download and install the app. Also note that my macbook runs much cooler now and much less fan noise. Shows only the integrated card in use. Hi, I just experienced the white screen on reboot. I tried all of the above and nothing worked until I rebooted in Verbose mode. Then shut down and it restarted OK.

What will happen when I chose, for example, El Capitan to start from? The introduction of the SIP-factor on the installation procedure cause me a lot of fuss. Many thanks in advance for your reply. I always get, after a long period of wait, a flashing question mark. No hardware problems interface circuitry and physical state of platters. The same happens with any external HD linked via the FireWire port.
So i have tried alot. I am lost……help anyone. I only started having this problem when I enabled FireVault. The rest of you with this problem white screen at start up requiring password , did you enable FireVault? I have OS Sierra. Curiously Apple does not address the white screen problem at all on their page about screens you might see during boot. You would think it does not exist, but I have seen it too as well as the black screen. I assume it is a software bug. I too will never go back to MS.
If I need something there rarer and rarer , I use VMWare Fusion and a selection of images with needed software ready to go. I have fixed a few machines by slaving then to my mac via Target disc mode and clearing the extensions folder in Library in root. With a restart the extensions that are default are re added and the culprits are gone. Before you try any of the above, I had a white screen problem on my iMac after an update, which caused me a lot of grief, and resulted in reinstalling my system.
When it happened again on the next updated, I was lucky enough to notice that I recognised the sound being made when I tried the keyboard. Sure enough, it was working properly, just not displaying. I then restarted the iMac and everything was OK. Whatever caused the video problem, I was not fixing it by repeatedly aborting the update. I just had to allow the process to finish and that solved it. The moral to the story is that there is an extra step of trying to Screen Share before you start to panic. That worked. I would love to find out if I can fix the white screen.
Someone out there fix this issue! Please explain how to reboot the Mac. The reason Verbose mode works is likely the fact that it is using the graphics display.click
